2. Light has a wavelength of 480.0 nm and a frequency of 4.69 X 10 Hz when traveling through a certain substance. What substance from Table 26.1 could this be? Diamond Glass, crown rice (0°C) sodium chloride quartz, fused Benzene Carbon disulfide Carbon tetrachloride Ethyl alcohol Water 3. A flat sheet of crown glass has a thickness of 1.9 cm. It is on top of a flat sheet of diamond that has a thickness of 1.8 cm. Light strikes the crown glass perpendicularly and travels through it and then through the diamond. In the time it takes the light to travel through the two sheets, how far would it have traveled in a vacuum? cm 4. A ray of light impinges from air onto a block of Ice (n = 1.309) at a 45.0° angle of incidence. Assuming that this angle remains the same, find the difference 2.ice-3, water in the angles of refraction when the ice turns to water (n = 1.333). O2, Ice - O2, water
